KHACHIMO PWS-406P-1R 400W ATX supply

The KHACHIMO PWS-406P-1R is a 400W ATX power supply built for standard desktop builds. It delivers the rated output through a conventional switching design that has been test-working verified. This unit suits system integrators and DIY builders who need a straightforward, new power source for mainstream configurations.

Suits mainstream ATX builds.

This supply fits typical office or home PCs with modest graphics and a single CPU. Builders planning multi-GPU arrays, heavy overclocking or workstations that draw sustained loads above the rated 400W should look at higher-capacity units instead.

400W continuous capacity with standard ATX headroom

The 400W rating provides comfortable headroom for mid-range processors and entry-level discrete cards under normal workloads. Continuous operation near the maximum limit reduces available reserve for transient spikes, so systems with power-hungry components may hit the ceiling during peak demand.

Questions about this item

What existing ATX case and motherboard power connectors are required to install this 400W unit?

It fits a standard ATX chassis and connects to a 24-pin main power socket plus the CPU and peripheral leads your board already provides.

Can the PWS-406P-1R run in a system that still uses older 20-pin motherboards or legacy drives?

The supply follows the ATX form factor; adapters are widely available if your board or drives need the older 20-pin or Molex connectors.

After fitting the supply, how can I verify the 400W PWS-406P-1R is operating correctly?

The system should POST reliably, fans spin steadily, and the unit runs without unexpected shutdowns under normal load.
